∙ 6y ago60 and 80 :D
63, 64
60, 72, 84, 90 and 96 each have twelve factors.
62 and 63 are two examples.
It is composite.
90 has factors other than 1 and itself, so it is not a prime number. For example, 90 is 9 x 10, so it is a composite number.
60, 72, 84, 90 and 96 each have twelve factors.
Assume you want to know if every number between 1 and 90 is a composite number. No, not every number between 1 and 90. Take 2 for instance. Then, 2 is prime since the factors of 2 are 1 and itself! * * * * * Assumed wrong! In the 90s refers to 90-99, but the answer is correct, because 97 is a prime.
90, 91, 92, 93, 94, 95, 96, 98, 99, 100 (including 90 and 100)
Composite numbers have factors other than 1 and itself. So, two good examples are: 62 and 84
As an even number greater than 2, 90 is divisible by 2 and therefore composite.
60, 62, 63, 64, 65, 66, 68, 69, 70, 72, 74, 75, 76, 77, 78, 80, 81, 82, 84, 85, 86, 87, 88, 90 are the composite numbers in that range.
